The Thief Vault is a slightly modified or hybrid movement of the Lazy Vault and the Dash Vault. It is less well-known and is considered by some to not be a useful technique or even a proper movement. It is used as a slightly faster alternative to the Lazy Vault, and the exit is more perpendicular to the obstacle as in a Dash Vault, rather than being parallel to the obstacle as in a Lazy Vault.
- Approach the obstacle as you would in a lazy vault, with the inside arm on the obstacle.
- Jump off using your inside leg, and rather than swinging it over the wall, swing your outside leg up and over before the inside leg.
- Place the other hand behind you, keeping the elbow bent not straight to absorb the impact.
- Push off with your hands and exit in the same way you would in a dash vault; with your legs split, and come out running (or use an appropriate landing if necessary).
